You need to migrate a UFS file system named /production_ufs to a ZFS file system named
/production_ufs. The /production_ufs file system cannot be taken down or be out of production duringthe migration,and the current /production_ufs file system must remain active until the /ptoduction_zfs file system is copied and ready.
Which method allows you to meet both requirements?
Copy live data from /production_ufs to /production_zfs while /production_ufs is in use.
When the copy is complete,/production_zfs will contain an up-to date copy of
Create a snapshot of the UFS file system. Create the new ZFS file system. Use cpio to copy data from the snapshot to the new ZFS file system.
Create a new Boot Environment. Create the ZFS file system. Use lucreate -m to copy data from the Current UFS file system to the new ZFS file system.
Mirror the existing UFS file system by using SVM.After both submissions are in sync,migrate one of the submissions to a ZFS file System by using Live Upgrade.
Create the new ZFS file system by using zfs create import to import data from the existing UFS file system into the new ZFS file system
Create the new zfs file system by using the zfs create -o shadow.
Answer: E Explanation:
Migrating Data With ZFS Shadow Migration
ZFS shadow migration is a tool you can use to migrate data from an existing file system to a new file system. A shadow file system is created that pulls data from the original source as necessary.
You can use the shadow migration feature to migrate file systems as follows:
A local or remote ZFS file system to a target ZFS file system
A local or remote UFS file system to a target ZFS file system
Shadow migration is a process that pulls the data to be migrated:
Create an empty ZFS file system.
Set the shadow property on an empty ZFS file system,which is the target (or shadow) file system,to point to the file system to be migrated.
# zfs create -o shadow=nfs://system/export/home/ufsdata users/home/shadow2
Data from file system to be migrated is copied over to the shadow file system.

User1 is attempting to run the following command: cp bigfile verybig
The system displays the following errer:
cp: cannot create verybig: Disc quota exceeded
Your initial troubleshooting shows that the df -h command indicates the account is at 100% capacity. What command would you use to determine how much disk space the user has available?
zfs get quota rpool/export/home/user1
zfs quota=1M /rpool/export/home/user1
df -h | grep user1
Answer: A Explanation:
ZFS quotas can be set and displayed by using the zfs set and zfs get commands. In the following example,a quota of 10 Gbytes is set on tank/home/bonwick.
# zfs set quota=10G tank/home/bonwick
# zfs get quota tank/home/bonwick NAME PROPERTY VALUE SOURCE
tank/home/bonwick quota 10.0G local

When you issue the “gzip: zommand not found” message is displayed. You need to install the gzip utility on your system.
Which command would you use to check if the gzip utility is available from the default publisher for installation?
pkg info|grep gzip
pkg list SUNWgzip
pkg contents gzip
pkg search gzip
Answer: D Explanation: Searching for Packages
Use the pkg search command to search for packages whose data matches the specified pattern.
Like the pkg contents command,the pkg search command examines the contents of packages. While the pkg contents command returns the contents,the pkg search command returns the names of packages that match the query.
search [-HIaflpr] [-o attribute …] [-s repo_uri] query Search for matches to the query,and display the results. Which tokens are indexed are action-dependent,but may include content hashes and pathnames.
Note: pkg is the retrieval client for the image packaging system. With a valid configuration,pkg can be invoked to create locations for packages to be installed,called #39;images#39;,and install packages
into those images. Packages are published by publishers,who may make their packages available at one or more repositories. pkg, then,retrieves packages from a publisher#39;s repository and
installs them into an image.

New features wore added to ZFS in Oracle Solaris11. Your justification to upgrade from Solaris10 to oracle Solaris11 is that it will be possible to take advantage of the enhancements that were made to ZFS.
Identify the three ZFS functions and features that are included in Oracle Solaris 11,but not in Solaris 10.
Encrypted ZFS datasets
Ability for ZFS to detect and remove redundant data from the tile system
Shadow Data Migration
Ability to split a mirrored ZFS storage pool
Ability to use ZFS on the boot drive and boot to a ZFS root file system.
elimination of the swap file system when using ZFS on the root disk
Answer: A,B,E Explanation:
A: ZFS encryption was introduced in ZFS Pool Version Number 30,Solaris Nevada b149. Filesystem encryption since Solaris 11 Express
B: Deduplication was introduced in ZFS Pool Version Number 21,Solaris Nevada b128. E: Booting From a ZFS Root File System
Both SPARC based and x86 based systems use the new style of booting with a boot archive,which is a file system image that contains the files required for booting. When a system is booted from a ZFS root file system,the path names of both the boot archive and the kernel file are resolved in the root file system that is selected for booting.

The core dump configuration for your system is:
A user is running a process in the global zone and the process crashes. The process information is:
User1 2663 2618 0 17:46:42 pts/2 0:00 /usr/bin/bash The server host name is: zeus
What will the per-process core file be named?
Answer: C Explanation: Note the first line:
global core file pattern: /globalcore/core.%f.%p
The program name is bash The runtime process ID is 2663
Note: By default,the global core dump is disabled. You need to use the coreadm command with the -e global option to enable it. The -g option causes the command to append the program name(%f) and the runtime process ID (%p) to the core file name.

Which three statements accurately describe the Automated Installation (AI) client?
If the AI client does not match any criteria to use a custom manifest or script,the default manifest is used.
If the AI client does not match any criteria to use a custom manifest or script,the automated installation aborts.
Any manifest or script in a service can be designated to be the default for that service.
Only the default.xml file is used as the default AT client manifest.
If a client system does not use any SC profile,then an interactive tool opens on that client at first boot after that client installation to complete the configuration of that client.
If a client system does not use any SC profile,then the install server will use the default SC profile.
Answer: A,D,E Explanation:
A: Each client uses one and only one AI manifest to complete its installation. The AI
manifest is selected for a client according to the following algorithm:
If no custom AI manifests are defined for this install service,the default AI manifest is used. The default AI manifest is not associated with any client criteria etc.
D: When you create a new install service,install_service_image_path/auto_install/manifest/default.xml is the initial default AI manifest for that install service.
E: Each client can use any number of system configuration profiles. If a client system does not use any configuration profile,then an interactive tool opens on that client at first boot after that client installation to complete the configuration of that client.

You have Solaris 11 system with a host name of sysA and it uses LDAP as a naming service.
You have created a flash archive of sysA and you want to migrate this system to an Oracle Solaris11 server,Solaris10 branded zone.
The zone Status on the Oracle Solaris 11 server is:
– zone10 incomplete/zone/zone1solaris10exc1
Select the option that will force the non-global zone to prompt you for a host name and name service the first time it is booted.
Use zonecfg to change the zonename before booting the system for the first time
Use the – u option with the zoneadm – z zone10 attach command.
Use the -u option with the zoneadn -z zone10 install command.
Remove the sysidcfg file from the lt;zonepathgt;/root directory before booting the non- global zone.
Answer: C Explanation:
Oracle Solaris 10 branded zones – Oracle Solaris 10 Zones provide an Oracle Solaris 10 environment on Oracle Solaris 11. You can migrate an Oracle Solaris 10 system or zone to a solaris10 zone on an Oracle Solaris 11 system in the following ways:
Create a zone archive and use the archive to create an s10zone on the Oracle Solaris 11 system.
This option applies in the current scenario.
Example of command to Install the Oracle Solaris 10 non-global zone. s11sysB# zoneadm -z s10zone install -u -a /pond/s10archive/s10.flar
Detach the zone from the Oracle Solaris 10 system and attach the zone on the Oracle Solaris 11 zone. The zone is halted and detached from its current host. The zonepath is moved to the target host,where it is attached.
install [-x nodataset] [brand-specific options] A subcommand of the zoneadm.
Install the specified zone on the system. This subcommand automatically attempts to verify first. It refuses to install if the verify step fails.
Unique identifier for a zone,as assigned by libuuid(3LIB). If this option is present and the argument is a non-empty string,then the zone matching the UUID is selected instead of the one named by the -z option,if such a zone is present.
